J., a corporation of New Jersey Application May 23, 1946, Serial No. 671,723 In Great Britain June 11, 1945 1 Claim.

This invention relates to machines for operating upon shoes and is herein illustrated as embodied in a machine adapted to perform a beating and bending operation upon the out-turned margins of the sole and upper of a turn shoe or slipper.

One well-known type of womens turn shoe slipper has a thin pliable sole that is secured inside out by a lock-stitch seam to an unlasted upper, usually of felt or cloth. The sewing operation results in causing the margin of the sole lying inside the margin of the upper to be turned up or bent outwardly from .a face of the s-ole. The deformation :of the sole is increased when, as is usual, a pad of material is laid on the surface of the sole and -a soft sock lining lis sewn to the edge of the upper while still in its inside-out condition. In order lto present a finished appearance the seam between the -sole and upper should present a regular line following substantially the feather or sole outline after the slipper has been turned right side out. Accordingly, it is desirable that the upturned margins of the sole and upper be made to lie substantially in the plane of the face of `the sole which will be inside the upper when the turning operation has been completed.

In view of the foregoing, it is an object of the invention to provide improved mechanism which is particularly effective in beating down and bending inwardly the outturned margins of the sole and upper of the shoe and at the same time one which is comparatively simple in its construction. To this end, and as illustrated, I have provided a machine in which there is -a support for an unlasted turn shoe, a reciprocating member movable toward and away from the support, and a hammer pivotally mounted upon the frame of the machine and having a portion positioned between the hammer and the support for operating upon the marginal portions of the sole and upper of the shoe, the arrangement being such that the hammer beats down the margins of the sole and upper and bends them inwardly so that they lie al-ong the plane of the face ofthe sole.

These and other features of the invention are illustrated in the following specication and in the accompanying drawing and are .pointed out in the claim.

The drawing is :a View in side elevati-on of the upper portion of a beating machine embodying one form of my invention.

The drawing shows mechanism operating upon an unlasted turn shoe or slipper ID having a sole l2 andan `upper lll, marginal edge portions ITB and I8 thereof, respectively, being secured together by stitches 2l). The purpose of the mechanism shown is to beat down and bend inwardly the upstanding portions of the sole and upper. This is accomplished by means of a hammer 22 actuated by plunger 24, there being a work support in the form of a horn 2-6 to support the shoe during the operati-on.

The hammer 22 constitutes the outer end of an arm 28 which is mounted upon a pivot 3l] carried by the machine frame 32. The hammer has a substantially flat work-engaging portion or face 34 adjacent to which i-s a recess 36 adapted to receive the side porti-on of the shoe or slipper adjacent to the seam. The hammer is urged upwardly by a spring 38 which maintains it continuously il; Icontact with the lower .portion of the plunger 2 The plunger 24 has an upwardly extending shank 4I) which is slidably mounted in 'bearings 42 carried by arms 44 extending laterally from the frame 32. The plunger is reciprocated by means of a loose collar 46 surrounding the plunger and connected to la drive shaft 48 by a crank 50, link 52 anda pi-n 54 `secured to the collar. The pin 54 is arranged for vertical reciprocation in a guideway 5E. Motion of the loose collar 46 is transmitted t-o the plunger by a compression spring 58 which bears upon a lower surface of the collar 4t and upon an adjustable ycollar 60 which can be secured in fixed position on the shank 40 by a lock nut 62. Dow-nward movement .of the shank 40 relatively to the loose collar 46 is limited by an adjustable collar 64 secured in position on the shank 40 by lock nut 6ft. The lower end of the plunger 24 is .provided with a facing of yieldable material 68, such as leather, to provide a suitable surface for engaging the upper side Iof the hammer 22.

The horn 26 is mounted upon a bracket 'l0 rotatable about the axis of a stud 12, heightwise adjustment of the horn being obtainable through operation of a hand nut 14. The upper end of the horn terminates in a button 16 arranged to support the work adjacent to the seam.

The construction and arrangement of the parts is such that `when the plunger is in its uppermost position the arm 28 and the work engaging face 34 of the hammer extend at an angle of about 45 to the horizontal with the face located between the plunger 24 -and the horn button 1li. Thus upon downward movement of the plunger the hammer will swing about its pivot to move the face 34 to-' ward and angularly across the button.

In the operation of the machine an unlasted turn slipper or shoe that is in inside-out condition is placed over the h-orn with the sole substantially in horizontal posi-tion and the slipper is moved the work support, and a spring operative to maintain the hammer in engagement with the plunger.
